Answer:
A. f(x) = x^2 + 4x + 3
D. f(x) = -2x^2 - 8x + 1
Step-by-step explanation:
The axis of symmetry is found by h = -b/2a where ax^2 +bx +c
A. f(x) = x^2 + 4x + 3
h = -4/2*1 = -2 x=-2
B. f(x) = x^2 - 4x - 5
h = - -4/2*1 = 4/2 =2 x=2 not -2
C. f(x) = x^2 + 6x + 2
h = -6/2*1 = -3/2 = x=-3/2 not -2
D. f(x) = -2x^2 - 8x + 1
h = - -8/2*-2 = 8/-4 =-2 x=-2
E. f(x) = -2x^2 + 8x - 2
h = - 8/2*-2 = -8/-4 =2 x=2 not -2
(1, -6) and (-5, 2)
Distance between 1 and -5 = 6
Distance between -6 and 2 = 8
6²+8²=x² (PYTHAGOREAN THEOREM)
36+64=x²
x² = 100
x = 10
Note: Not -10 because <em>distance cannot be negative.</em>
Step 1: Add 225 to both sides.<span><span><span>x−225</span>+225</span>=<span>550+225</span></span><span>x=775</span>Answer:<span>x=<span>775
If this is what your asking for, I got confused.

Answer:
£50.63
Step-by-step explanation:
If €4 = £3
Therefore one €1 = £3/4
Now, Converting €67.50 to pounds,
67.50 * 3/4 = £50.625
£50.63 (answer rounded to 2 DP)
Current time conversion,
67.50 Euro equals 60.68 Pound sterling
